Javacpp 1.5 build failed with Gradle #1311

onionf91 · 2019-10-05T03:22:14Z

Following configuration work perfect with Javacpp 1.4.x

tasks.compileJava.doLast {
    def projectDir = project.projectDir.absolutePath
    def jsonCppIncludeDir = "$projectDir/../external/modules/jsoncpp/include"
    javaexec {
        main 'org.bytedeco.javacpp.tools.Builder'
        classpath files(configurations.javacpp.asPath)
        args '-cp', tasks.compileJava.destinationDir,
             "-Dplatform.includepath=$projectDir/src/main/cpp:$jsonCppIncludeDir",
             "-Dplatform.root=$System.env.NDK/toolchains/llvm/prebuilt/linux-x86_64",
             '-Dplatform.compiler=bin/clang++',
             "-Dplatform.compiler.default=-O3 -s",
             '-Dplatform.compiler.output=-D__ANDROID_API__=28 -DANDROID -ffunction-sections -funwind-tables -fstack-protector-strong -target aarch64-linux-android28 -march=armv8-a -Wall -static-libstdc++ -fPIC -shared -Wl,--no-undefined -z text -o\u0020',
             '-Dplatform.link=log',
             "-Dplatform.compiler.srcJsonCpp=${jsonCppSource()}",
             '-Dplatform.library.path=lib/arm64-v8a/'
    }
}

But I got build failed exception as below since I upgrade Javacpp version to 1.5.x

Is there any migration guide for Gradle users?

It doesn't say much. We'll need more information to debug this.

onionf91 · 2019-10-05T05:49:35Z

If I add args' -print and /some/where/ then the task just exit and nothing to do. I guess the process exit by following logic:

//org.bytedeco.javacpp.tools.Builder.java
...
        if (printPath != null) {
            Collection<Class> classes = builder.classScanner.getClasses();
            ClassProperties p = Loader.loadProperties(classes.toArray(new Class[classes.size()]), builder.properties, true);
            builder.includeJavaPaths(p, builder.header);
            for (String s : p.get(printPath)) {
                System.out.println(s);
            }
            System.exit(0);
        } else if (!addedClasses) {
            printHelp();
            System.exit(2);
        }
...

If I don't put -print and /some/where as args, then gradle's javaexec just return exit code 2 and help info from javacpp. That's why can't I collect any further error message...

onionf91 · 2019-10-05T05:57:31Z

My Gradle configuration is execute javacpp's builder after compile java task, then specific compiled java classes by -cp argument. Its seems like 1.5.x version's builder will just exit with 2 and print help info when *.java file doesn't present on arg list.

… (issue bytedeco/javacv#1311)

saudet · 2019-10-06T14:29:27Z

I see what's missing. It used to process all classes by default, but this behavior was confusing, so now we need to specify the classes we want to process, just like it is for other tools like java or javac. If you like the previous default behavior, we should be able to add a .** as an additional argument to the command, as given by javaexec in your build file, but there is a bug preventing this from working actually. I've fixed it in commit bytedeco/javacpp@bdd18ef. Thanks for reporting!

onionf91 · 2019-10-07T01:21:59Z

Thanks a lot.

saudet · 2019-11-06T02:10:12Z

Bug fix included in just released JavaCPP 1.5.2! Thanks for reporting.

saudet · 2020-05-21T01:23:26Z

BTW, a build plugin for Gradle is now available here:
https://github.com/bytedeco/gradle-javacpp
If you try it out and find anything missing, please let me know!

onionf91 · 2020-06-27T06:33:23Z

I've tried it. It is pretty good and easy to use. I look forward to seeing it release and publish to maven central. Thanks for your effort and time.
